Abstract

The invention provides a fuel-assisted oil gun of a cement kiln pulverized coal burner, and belongs to the technical field of cement clinker production. The fuel-assisted oil gun comprises a fuel oil pipe, the fuel oil pipe is sleeved with a compressed air pipe, the oil outlet end of the fuel oil pipe is located in the compressed air pipe, and the oil outlet end of the fuel oil pipe is provided with a first-stage atomization assembly. The first-stage atomization assembly is sleeved with a mixing assembly used for mixing compressed air and fuel oil, the oil outlet end of the mixing assembly is provided with a second-stage atomization assembly, and the air outlet end of the compressed air pipe is provided with a third-stage atomization assembly. The fuel-assisted oil gun is simple in structure, good in fuel oil atomization effect, small in fuel oil consumption and good in pulverized coal combustion-supporting effect.

Description

technical field [0001] The invention relates to the technical field of cement clinker production, in particular to a fuel burner for a pulverized coal burner in a cement kiln. Background technique [0002] Cement kilns generally use pulverized coal as fuel, and oil guns are generally used to ignite and heat up when starting production. The oil gun is composed of a nozzle at the end and a connecting pipe at the back. Its key component is the nozzle. The nozzle not only satisfies the need to atomize the oil well under low pressure, but also plays a role in supporting the combustion of pulverized coal and meeting the requirements of cement Kiln ignition heating requirements. [0003] The atomization effect and adjustment performance of the oil gun nozzle directly affect the heating time and oil consumption of the kiln. At present, the oil gun nozzle of the domestic pulverized coal burner is divided according to the presence or absence of atomization medium. There are mainly si...
